Crosstalk between H3K4me3 and oxidative stress is a potential target for the improvement of ART-derived embryos

open access: yesNature Communications
With the advent and development of assisted reproductive technology (ART), more and more people affected by infertility have been able to obtain offspring successfully. Nevertheless, various adverse outcomes have been found to be associated with ART, and

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Rhapontigenin alleviates cellular senescence and physiological aging by upregulating sirt1 and promoting autophagy

open access: yesChinese Medicine
Background Aging is characterized by cellular senescence, inflammation, and physiological decline. Currently available antiaging therapies often have limitations due to their toxicity and off-target effects.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Elevated maternal pre-transfer serum lipid peroxidation is associated with implantation failure and early pregnancy loss

open access: yesBMC Medicine
Background Embryo implantation failure and early pregnancy loss remain significant challenges in assisted reproductive technology (ART). Lipid peroxidation is known to be involved in reproductive physiology.
